Noise, vibration, and harshness directly affect vehicle comfort, product quality, structural durability, and customer experience. In electric vehicles and modern mobility platforms, NVH performance has become even more important because the absence of engine noise makes motor noise, fan noise, compressor noise, tire noise, structural vibration, and cabin acoustic issues more noticeable.
NVH, Vibration & Acoustic Analysis helps automotive and electric mobility teams identify the sources of unwanted noise and vibration, understand how they travel through vehicle structures, and improve designs before prototype testing. By using simulation-led engineering, Experiqs helps reduce resonance, vibration transfer, buzz, squeak, rattle, flow-induced noise, and structural-borne acoustic issues.
Experiqs provides NVH, Vibration & Acoustic Analysis services for automotive OEMs, EV manufacturers, mobility startups, component developers, and engineering teams. We use vibration analysis, acoustic simulation, structural dynamics, modal analysis, flow-induced noise evaluation, motor noise studies, and simulation-led design optimization to improve vehicle comfort, reliability, and perceived quality.
Vehicle NVH performance is influenced by many interacting sources, including motors, compressors, cooling fans, tires, ducts, panels, mounts, battery packs, powertrain systems, suspension components, and vehicle body structures. These sources can create vibration, resonance, airborne noise, structural-borne noise, and cabin noise issues.
In electric vehicles, NVH challenges are different from conventional vehicles. Electric motors can generate tonal noise, inverters can contribute high-frequency acoustic signatures, cooling fans and compressors become more noticeable, and structural-borne paths from battery packs or powertrain mounts can affect cabin comfort.
Poor NVH performance can reduce perceived quality, increase driver fatigue, create customer complaints, and indicate structural or mounting issues. Vibration can also affect durability by increasing fatigue risk in panels, mounts, brackets, battery enclosures, and powertrain components.
Simulation-led NVH analysis helps identify vibration sources, acoustic paths, resonance frequencies, structural response, and design weaknesses before physical testing. Experiqs helps automotive teams reduce NVH risks early and develop quieter, smoother, and more reliable vehicles.
We evaluate the dynamic response of vehicle structures, mounts, panels, battery packs, motors, and powertrain systems under real-world operating conditions.
Our analysis helps assess:
• Vehicle structure vibration
• Mount and bracket response
• Panel vibration behavior
• Battery pack vibration response
• Motor and powertrain vibration
• Suspension-induced vibration effects
• Resonance-prone regions
• Dynamic load transfer paths
This analysis helps identify vibration-sensitive areas, reduce vibration transfer, and improve overall vehicle durability, performance, and ride comfort.
We predict and analyze noise from motors, fans, compressors, tires, ducts, body panels, and structural-borne paths.
We help evaluate:
